ELASTIC TIRE.

SPECIFICATION forming part of Letters Patent No. 688,994, dated December 1'7, 1901. Application filed September 9, 1901. Serial No. 74,800. (No model.)

To all whom it may concern.-

Beit known that I, THOMAS GARE, a subject of the King of Great Britain, and a resident of New Brighton, in the county of Chester, England, (whose post-office address is Bramble Beach, Warren Drive, New Brighton,) have invented new and useful Improvements in and Connected with Elastic Tires, (for which I have made application for patent in Great Britain, No. 3,734, dated February 21, 1901; in France, dated June 20, 1901; in Belgium, dated June 20, 1901; in Germany, dated June 21, 1901; in Austria, dated June 19, 1901; in Hungary, dated June 19, 1901; in Italy, dated August 21, 1901, and in Switzerland, dated August 21, 1901,) of which the following is a specification.

My invention relates to improvements on an invention for which Letters Patent No. 665,203, dated January 1,1901,were granted to me, and has for its object to provide the tube or ring forming the Wearing surface of the tire described and shown in the specification belonging to the said patent with a wearing-surface which is readily renewable and greatly prolongs the life of .thetire. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figures 1, 2, 3, and 4 are cross-sections of tires; and Fig. 5, a side view, partly in section, of a wheel complete at a reduced scale. Figs. 6 and 7 are two modifications of the removable wearing-surface. H

Similar letters refer to similar parts throughout the several views.

In carrying out my invention and referring to the figures generally, a is the channeled rim; b,the rubber bed therein,havinga groove 0; (Z, the open tubular ring; e, the improved wearing-surface of the tire. Now instead of using the open tubular ring (Z as a wearingsurface I use an endless metal ring 6, of suitable section, which I shrink onto the periphery of the said tubular ring. This outer ring e forms the actual wearing-surface, while the tubular ring d forms simply an intermediate body between the elastic bed Z) and the wearing-surface e, which intermediate body allows the wearing-surface c to be renewed. This intermediate body, being rigid, prevents the wearing-surface e breaking through torture and allows the latter to be shrunk on without destroying or deteriorating the rubber bed I).-

The rubber bed I) thoroughly insulates the ring or wearing-surface e from the channeled rim, and thus from the wheel and vehicle, which renders the wheel free from jars and vibration. The wearing-surface 6 also provides increased security of the intermediate body (2 in its elastic bed I).

Fig. 1 shows an oval and Figs. 2 and 3 a partly flat sectioned tubular-ring d, the wearing-surface e being semicircularin Figs. 1 and 3 and in Fig. 2 nearly straight.

When using my improved tire to run on rails, I form the ring or wearing-surface 6 with a flange 1' or on the channel-rim a, as shown in dotted lines, Fig. 2.

Instead of using an intermediate body din a tubular form I may use a semicircular or similarly-sectioned open metal ring f in the elastic bed or seat I), as shown in Fig. 4, to the outer periphery of which I then shrink the metal ring 6, forming the actual wearing-surface.

The ends of the intermediate ring or body (2 I suitably connect together, say, by a tongue g, engaging in the ends thereof, and pins 72, passed crosswise through the tongue g and ring or body, (see Fig. 5,) so as to prevent the latter leaving the elastic bed or seat I) should the ring or wearing surface 6 have Worn through at the joint of the intermediate ring or body cl unnoticed.

To prevent the wheel skidding (slipping) laterally or axially, the wearing-surface 6 may be formed with grooves, as shown in Figs. 6 and 7, which in some cases may be filled with leather or the like. (See Fig. 7.)

WhatI claim as my invention, and desire to secure by Letters Patent, is-

In an elastic tire of the type hereinbefore specified, the combination of an outer endless ring 6 with an intermediate tubular open ring 61 cramped into the groove sides of a rubber bed 0 in a channeled rim a, the said outer endless ring being shrunk onto the said intermediate tubular open ring and forming a renewable wearing-surface for the latter, all substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.
